Pakistan and Indian will hold talks Sunday in Thimphu, capital of Bhutan, when Foreign Secretary Nirupama Rao and her counterpart Salman Bashir meet six months after they held talks in Islamabad, said local media. New Delhi is expected to seek an update on Mumbai terror attacks probe and trial, while Pakistan has asked India to solve the Samjhauta Express train blast case in 2007, in which Hindu radicals were allegedly involved, to the Mumbai attacks case. India has rejected the demand of Pakistan, saying the two cases were not comparable, and there were clear leads in the Mumbai incident unlike in the cross-border train attack case, said Press Trust of India. India and Pakistan resumed foreign secretary level talks in Feb. 2010 in New Delhi, after they suspended official dialogue following the Mumbai attacks in Nov. 2008.
